Anyone Ever Seen This Piece

Wood grain window crank escutcheons.

I'm trying to find 3 more of these for my E body. Not having any luck with the Google machine. So, I'm hoping one of the old timers can point me in the right direction.

I can see where the escutcheon wore a ring into the door panel, so I was thinking they might have come from the factory when the car was new.

Any ideas where to get 3 more?

Thank you.
